Princess Elisabeth of Poland (Polish: Elżbieta Kazimierzówna; 1326–1361) was the eldest child of Casimir III of Poland and his first wife, Aldona of Lithuania.
Elizabeth was originally betrothed to her future brother-in-law, Louis VI the Roman. She was eventually passed over for her younger sister, Cunigunde.
An agreement, directed primarily against the Teutonic Order, was reached on 24 February 1343 in Poznań between Elizabeth's father and Bogislaw V, Duke of Pomerania. As a result, Elizabeth married Bogislaw on 28 February 1343. She received a dowry from her father of 20,000 kop (cents in Prague) and mainly lived in the Castle of Darlowo during her marriage. The couple had two children:
Her daughter Elizabeth was married in 1363 to the Holy Roman Emperor Charles IV. The marriage took place during the Congress of Kraków; the most celebrated feast commemorating the event took place at the house of Mikołaj Wierzynek (młodszy). Elizabeth of Poland did not live to see her daughter married off. She died in 1361 at a monastery of the Order of Saint Augustine in Świątkach, and was buried there.
Her son, Casimir (Kaźko) was groomed to become Casimir the Great's successor as King of Poland but was sidelined by Louis I of Hungary, and instead succeeded Bogislaw in 1364 as Duke of Pomerania.
